Description

Technical Field

[0001] The utility model relates to the technical field of smelting equipment, in particular to a welding copper bottom ring. Background Art

[0002] The copper bottom ring is one of the important parts of the combined electrode holder of the submerged arc furnace. It is installed at the bottom of the motor holder and is mainly used to prevent the high-temperature flue gas from ablating the conductive tubes, contact elements and other parts inside the electrode holder. It is of great significance to the safe and economical operation of the submerged arc furnace.

[0003] At present, most commonly used copper bottom rings adopt welding to fix various components, so as to facilitate the processing of the cooling water flow channel inside. For example, the patent with announcement number CN216898404U discloses a bottom ring of an industrial silicon furnace electrode holder, which is provided with a semicircular monomer, two coaxially arranged semicircular water-proof vertical plates are arranged inside the semicircular monomer, and inner sealed water-proof plates are arranged at both ends of the semicircular water-proof vertical plates to form a serpentine flow channel. By arranging a water inlet pipe and a water outlet pipe, the water inlet pipe injects cooling water into the interior of the semicircular monomer, and the water flows out from the water outlet pipe through the serpentine flow channel. The water channel is tightly closed without any gaps, and the water flow does not take shortcuts, which will not cause the water flow in the water channel outside the bottom ring to be stagnant. The three water channels are heated evenly, the entire bottom ring is heated evenly and does not deform, the outer side of the bottom ring will not be dry-burned, and the service life of the bottom ring is extended.

[0004] Although the above scheme forms a serpentine flow channel in the bottom ring, it has a large number of components, a large welding workload, and a high cost. In addition, since some welds are located on the inner side of the bottom ring, it is difficult to ensure full welding of the welds, and welding defects are prone to occur, resulting in shortcuts in the serpentine flow channel, making it impossible for cooling water to circulate in some parts of the bottom ring. This needs to be improved. Utility Model Content
